One of the practical op-amp limitations is the rate at which the output voltage can change. The limiting rate of change for a device is called its "slew rate". The slew rate for the 741 is 0.5V/microsecond compared to 100V/microsecond for a high-speed op-amp. The LH0063C has a slew rate of 6000V/microsecond. The slew-rate imposes high-frequency limitations on the device. At some critical frequency, an output swing equal to the supply voltages will require a slew rate faster than the maximum slew rate of the device. Above that frequency, the amplitude of distortion-free output voltage swing will be limited.
The slew rate is inherently limited by the small internal drive currents of an op-amp but is also limited by internal capacitance designed to compensateagainst high frequency oscillations. Some op-amps are externally compensated and therefore offer some control over the slew rate.

How can you calculate the evaporation rate of your swimming pool?
To calculate the evaporation rate of your swimming pool, you can use a simple formula: Evaporation Rate = (Pool surface area) x (Evaporation rate factor) x (Temperature difference). Measure the surface area of your pool, find the evaporation rate factor for your area, and determine the temperature difference between the pool water and the air. Multiply these values to calculate the evaporation rate.
How can we calculate the time it takes to travel if we know distance and rate?
You can calculate the time it takes to travel by dividing the distance by the rate. The formula is time = distance / rate. This will give you the time in hours it takes to travel the given distance at the given rate.
How to calculate flow rate in a pipe system?
To calculate flow rate in a pipe system, you can use the formula Q A V, where Q is the flow rate, A is the cross-sectional area of the pipe, and V is the velocity of the fluid. You can measure the area of the pipe and the velocity of the fluid to determine the flow rate.
How can one calculate pressure from flow rate?
To calculate pressure from flow rate, you can use the formula: Pressure Flow Rate x Resistance. The resistance is typically represented by the diameter and length of the pipe through which the fluid is flowing. By knowing the flow rate and resistance, you can determine the pressure of the fluid in the system.
How can I calculate the psi (pounds per square inch) from a given flow rate?
To calculate the psi from a given flow rate, you can use the formula: psi (flow rate in gallons per minute) / 2.31. This formula helps you convert the flow rate into pressure in pounds per square inch (psi).
What ia the applicatoin of slew rate?
A: The application is for DAC ADC converters where the fastest slew rate is desirable for fast conversion
What is slew rate in operational amplifier?
the slew rate of an op-amp represents the maximum rate at which the output can change , no matter how large an input signal is applied the slew rate of an op-amp is specified in V/s or V/mew second.
What is slew rate?
slew rate is the ability of an amplifier to reproduce amplified version of the input signal in terms of frequency and phase. The input signal amplitude change is fast. But the amplifier will take some time to give response to the changes in input signal. i.e. how fast the amplifier tracks the input signal is the slew rate. For an amplifier the slew rate should be high in order to avoid signal distortion. The rate of change of the output voltage of an amplifier for the given input signal change is called the slew rate.
What is the slew rate of 741ic?
0.5V/us
What are the causes of slew rate?
slew rate is caused by current limiting and the saturation of internal stages of an op-amp when a high-frequency,large amplitude signal is applied.
You want 741IC circuit with perfect value for 50 percent squre wave signal?
you cannot ever achieve that . the 741 has inherited storage time due to overdrive and the slew rate is not exactly fast. it can be done provided by tweaking the input drive and selecting amplifiers
How is slew rate affect on amplifier?
as it is rate of change of output voltage..so it affect amplifier output
Why IC741 is not used for high frequency applications?
IC741 has a low slew rate because of the predominance of capacitance present in the circuit at higher frequencies. As frequency increases the output gets distorted due to limited slew rate.
What can be multiplied to get 741?
1 x 741 = 741 3 x 247 = 741 13 x 57 = 741 19 x 39 = 741
What is 225 percent of 741?
225% of 741 = 225% * 741 = 2.25 * 741 = 1,667.25
What is the formula to calculate the rate of osmosis?
how do you calculate the rate of osmosis
Is the slew rate of the non-inverting amplifier the same as the voltage follower?
It can be but it might not be, it depends on circuit design.
